i. Blower wiring is faulty or disconnected.
ii. Blower needs replacing. Check blower.
iii. The thermostat or blower may have failed and the thermal overload device is controlling the temperature.
Stop using the cabinet immediately and contact a factory-approved service agent.
3. Temperature too low:
a. The cabinet may still be in pre-heat or recovering from a door being opened.
b. Temperature set point is too low. Turn temperature control knob to a higher setting. Wait several minutes and
see if the displayed temperature increases.
c. A door is not closed or sealing properly.
d. Blower is not circulating air:
i. Blower wiring is faulty or disconnected.
ii. Blower needs replacing.
4. Indicator light is not working:
It is rare that an indicator light will be defective but it is possible. The thermostat contacts may not be closing
and therefore the heater element is not being energized. Check the thermostat and pilot light and their
respective wiring.
5. No heat generated:
a. If the heat indicator light is on, but the cabinet does not draw the appropriate amperage per the chart on
page 11.
i. Air heater element may be faulty.
ii. The wiring to the air heater element may be faulty or disconnected.
iii. The thermostat may be faulty.
b. If the heat indicator light is not on, the thermostat contacts may not be closing and therefore the heater
element is not being energized. It is rare that the indicator light will be defective but it is possible. Check the
thermostat and pilot light and their respective wiring.
6.Moisture level is too low:

a. If the heat indicator light is on, and the cabinet draws the appropriate amperage per the chart on page 11:
i. Check that the stainless steel water pan has water.
ii. A door is not closed or sealing properly.
iii. Moisture set point is too low. Turn moisture control knob to a higher setting.
b. If the heat indicator light is on, but the cabinet does not draw the appropriate amperage per the chart on
page 11:
i. Air heater element may be faulty.
ii. The wiring to the air heater element may be faulty or disconnected.
iii. The thermostat may be faulty.
c. If the heat indicator light is not on, the thermostat contacts may not be closing and therefore the heater element
is not being energized. It is rare that the indicator light will be defective but it is possible. Check the
thermostat and pilot light and their respective wiring.
7. Cabinet trips GFCI (ground fault circuit interrupter):
A GFCI receptacle protects against “ground faults” whenever an electrical product is plugged into the GFCI
outlet by constantly monitoring the electricity for any loss of current. If the current flowing out of the receptacle
differs by a small amount from that returning, the GFCI quickly switches off power to that circuit. The GFCI
interrupts power extremely fast to minimize the possibility of an electric shock.
a. The heater element may absorb some moisture into its casing and insulation during shipment or during long
periods of not being used (such as during the summer in a closed school kitchen). Plug the cabinet (without
water in the stainless steel water pan into a non-GFCI outlet, set the temperature to “10” and let it run for
30-60 minutes to dry out any moisture the element may have absorbed. (If it trips the standard circuit breaker
call factory-approved service agent.) After drying the element, plug the cabinet into the GFCI outlet; the
cabinet should run without tripping the GFCI.
b. If the cabinet still trips the GFCI, call a factory-approved service agent.
